Abstract: Abstract of the Disclosure An inner sleeve is used in a tubing joint assembly with this inner sleeve having a lateral shoulder generally perpendicular to the axis of the sleeve and with this shoulder terminating in a sharp angled peripheral rib.  A tube is telescoped over this inner sleeve.  An outer sleeve may optionally be telescoped over the tube and the entire assembly inwardly compressed by two dies which have inter-digitated teeth.  This compresses the outer sleeve, where used, and compresses the tube onto the peripheral ribs of the inner sleeve.  The interdigitated teeth on the dies assure complete compression all the way around the periphery of the tube onto the inner sleeve with a lateral shoulder being formed on the tube to act against the lateral shoulder on the inner sleeve and thus longitudinally retain together these parts.  Also a fluid pressure tight seal is established primarily at the sharp angled peripheral rib and its junction with the inner wall of the tube.

Abstract: ABSTRACT OF THE DISCLOSURE A competitive protein binding method is provided for the determination of an analyte which is a member of an immunological pair consisting of ligand and receptor for the ligand.  A chemiluminescent source is employed comprised of one or more individual members, one chemiluminescent source member being conjugated to one of the members of the immuno-logical pair, so as to provide chemiluminescence adjacent to the site of conjugation.  A quencher molecule is conjugated to a member of the immunological pair.  When the members of the immunological pair bind, the quencher molecule is brought within quenching distance of the chemiluminescent source so as to inhibit the emission of light by the chemi-luminescent source.  The amount of analyte present in the assay medium affects the amount of binding between the members of the immunological pair which results in quenching of the chemiluminescence.  By observing the light emitted from the assay medium, either from the chemiluminescent source or the quencher, the change in light emission in relation to the concentration of analyte present in the assay medium can be used to determine the amount of analyte present in the assay medium.  By employing standards having known amounts of analyte, the amount of analyte in an unknown sample can be quantitatively determined.  Reagent kits can be provided having predetermined amounts of the reagents, so as to substantially optimize the sensitivity of the assay.

Abstract: ABSTRACT OF THE DISCLOSURE:         The invention is concerned with a method for the adaptation of hydrophilic-gel contact lenses into a planarized state, which comprises clamping a lens swollen by a volatile swelling agent between two planar or moderately curved surfaces, at least one of which is formed by a thin foil permeable to the volatile swelling agent, and then allowing the swelling agent to penetrate through the permeable foil whereby the lens is transformed into a xerogel state.  The lens which is shaped into the planarized form in a strongly swollen state is much softer than the lens heated to a narrow temperature range between the softening temperature and the decomposition tempera-ture of dry gel in the high-temperature planarization.  Conse-quently, the swollen lens adapts much more precisely even to the finest structures of surfaces between or to which it is clamped, thus allowing to form any fine drawings on the lens, which are permanently preserved in the dry state under the common atmospheric conditions and which completely disappear by reswelling.

Abstract: 6.2.1979                      1                      PHN. 9203 ABSTRACT:                 Method of positioning reproducing elements and device for carrying out the method.                  In video recorders where the video information is alternately recorded in oblique tracks by means of two heads, there are generally provided fine control mechanisms for centering the heads relative to the track to be followed. These mechanisms do not detect whether  the two heads occupy a correct position relative to each other; the position of the heads relative to each other  may differ by an amount corresponding to one track or a group of tracks. The method of controlling the two heads so that they occupy a correct position relative to each other assumes the use of a recor-ding medium for which the signals reproduced by the heads contain such pilot signals that in the case of a correct reading of two consecutive tracks the pilot signals read are spaced at a nominal. time interval from each other, i.e. half the revolution period of the head disk. The time inter-val between the detection of two consecutively read pilot signals is measured and if said time interval deviates from the nominal time interval to a predetermined extent, the position of the two heads relative to each other in a direction transverse to the recording tracks is corrected.

Abstract: "ADAPTIVE TEMPERATURE CONTROL SYSTEM"                   ABSTRACT OF THE DISCLOSURE         A refrigerator includes a compressor, a condenser fan, and an evaporator fan simultaneously energized by a temperature control system which includes a thermistor located to sense the average temperature of the cabinet air and a potentiometer manually adjustable to a desired temper-ature set point.

The off time is adaptively controlled within a predetermined range which minimizes energy consumption while maintaining good temperature control.  An off time counter, which is used to determine the duration of the off cycle, is incremented when the measured run time is less than a desired minimum, is decre-mented when the measured run time is greater than a desired maximum, and maintains the prior off time when the measured run time is within a desired range.

Abstract: Abstract of the Disclosure An ultrasonic flowmeter of the upstream/downstream sonic propagation type includes two transducers mounted externally on the same side of a flow conduit.  The transducers are coupled to re-spactive sonic probes which transmit and receive acoustic pulses between the transducers through the fluid by "bouncings the pulses off the opposite pipe wall.  Additionally the meter maintains a smooth bore in the measurement region so that the acoustic pulses are refracted at the probe/fluid interface and hence propagate along a sonic path that varies depending on the sonic velocities within the fluid and the probe.  An acoustic path of known length is included within at least one of the probes along which a portion of the generated acoustic pulses propagates, thereby providing for a third sonic measurement which represents the transmit time in the probe.  The three sonic propagation time  measurements are neces-sary and sufficient to specify the flow velocity independent of sound velocity changes in the fluid and the probe and hence of changes in the path of propagation.

Bus allocation is achieved by placing each request from a device for control of the resource in an ordinal ranking with respect to requests from other devices.  Requests are assigned positions in the ordinal ranking concurrent with other activity on the data bus.  Substantially simultaneous requests are ordered sequentially.  As control of the data bus is relinquished by one device, control is transferred to the device whose position in the ordinal ranking is contiguous with that of the relinquishing device. Delay in making this transfer is substantially eliminated.
